400G Ethernet demos, plugfest tout hyperscale network power

High-speed Ethernet is taking center stage this week at the European Conference on Optical Communication in Rome, Italy where a number of vendors including Arista, Cisco and Huawei are showing off gear that will power large-enterprise and hyperscale networks.The key demos come from the Ethernet Alliance and the 100G Lambda multisource agreement (MSA) group that are pushing technology advances needed to support 400G Ethernet, including new pulse amplitude modulation or PAM4 for electrical and optical interfaces, high-bandwidth switching silicon and a new high-density pluggable connector system known as QSFP-DD.To read this article in full, please click here

ICANN sets plan to reinforce internet DNS security

In a few months, the internet will be a more secure place. That’s because the Internet Corporation for Assigned Names and Numbers (ICANN) has voted to go ahead with the first-ever changing of the cryptographic key that helps protect the internet’s address book – the Domain Name System (DNS). [ Now see: The hidden cause of slow internet and how to fix it. ] The ICANN Board at its meeting in Belgium this week, decided to proceed with its plans to change or "roll" the key for the DNS root on Oct. 11, 2018. It will mark the first time the key has been changed since it was first put in place in 2010.To read this article in full, please click here

What to expect when the internet gets a big security upgrade

Ready or not, the upgrade to an important internet security operation may soon be launched. Then again, it might not.The Internet Corporation for Assigned Names and Numbers (ICANN) will meet the week of Sept. 17 and will likely decide whether or not to give the go ahead on its multi-year project to upgrade the top pair of cryptographic keys used in the Domain Name System Security Extensions (DNSSEC) protocol — commonly known as the root zone key signing key (KSK) — which secures the Internet's foundational servers.[ RELATED: Firewall face-off for the enterprise ] Changing these keys and making them stronger is an essential security step, in much the same way that regularly changing passwords is considered a practical habit by any Internet user, ICANN says. The update will help prevent certain nefarious activities such as attackers taking control of a session and directing users to a site that for example might steal their personal information.To read this article in full, please click here

Analysts: SD-WAN 5-year annual growth rate tops 40%

Whether users are looking to stabilize cloud-connected resources, better manage remote networks or simply upgrade a timeworn wide area environment, software-defined-WAN (SD-WAN) technologies are what’s on the purchasing menu.The proof lies in the fact that this segment of the networking market will hit $4.5 billion and grow at a 40.4% compound annual growth rate from 2017 to 2022. In 2017 alone, SD-WAN infrastructure revenues increased 83.3% in 2017 to reach $833 million, according to IDC's recent SD-WAN Infrastructure Forecast.  [ Click here to find out more about SD-WAN and why you’ll use it one day and learn about WANs and where they’re headed. | Get regularly scheduled insights by signing up for Network World newsletters. ] A related report from researchers at the Dell’Oro Group predicts revenue from SD-WAN software components, including controller and virtual network functions, will grow almost twice as fast as the hardware components.  Over the next five years, SD-WAN software revenue will grow at a 41% compounded annual growth rate, compared to 21% for hardware.To read this article in full, please click here

DHCP defined and how it works

The ability to network devices quickly and easily is critical in a hyper-connected world, and although it has been around for decades, DHCP remains an essential method to ensure that devices are able to join networks and are configured correctly. DHCP greatly reduces the errors that are made when IP addresses are assigned manually, and can stretch IP addresses by limiting how long a device can keep an individual IP address. [ Now read 20 hot jobs ambitious IT pros should shoot for. ] DHCP definition DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.To read this article in full, please click here
